Performance Exhaust Manifold Headers for 1999–2003 Ford 5.4L Powerstroke & 2004 Heritage F150

Description

The exhaust manifolds found in the 1999-2004 Ford F150 were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our 4-1 Long Tube off-road headers are designed to allow the exhaust gasses to flow more freely from each 4 cylinder bank and combine in a more efficient manner. Tubing has been optimized for the 5.4L(330ci) engine. This creates a reduction in cylinder backpressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound.
